I just received an e-mail from facebook saying "this is you on hidden cam" from one of my friends, and so I clicked on the link, but when I did I was prompted to download a file named codecsetup.exe. At this point I was suspicious so I googled it before downloading it and sure enough, it is a worm! Apparently the worm sends it out to everyone on your contact list, and the cycle continues. So if you receive a message from one of your friends asking you to click on a link, be careful! It may be a scam!
